BURNER.

1 0 all whom it may concern:

Be it knownthat I Louis C. BENNER, a citizen of the United btates,residing at T0- ledo, in the county ofLuoas and State of Ohio, haveinvented certain new and useful Improvements in Burners; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to an improved burner, for use in connection witha stove or heaterof the type disclosed in my prior Patent No. 1288807issued; December 2 1, 1918, and one object of the invention is toprovide a burner which may be formed in two sections releasablyconnected so that the sections of the burner may be taken apart when itis desired to clean the burner.

Another object of the invention is to so construct the burner that thekerosene or other liquid fuel will enter the burner at the outer end ofa nozzle forming aportion of the same and will pass throughpassages uponopposite sides of the nozzle to an outlet valve thus permitting theliquid fuel to be readily converted into a gas before entering the valvehousing.

.i-Lnother object ofthe invention is to so construct the burner that thenozzle thereof will be provided with a relatively wide and flat outlethaving a battle positioned therein to divide the flame and cause theflame to pass out of the nozzle in a wide and flat flame.

Another objectof the invention is to so construct this burner that thetwo sections will interlock and thus be braced against longitudinal ortransverse movement when the two sections are put together andsecured.

Another object of the invention is to so construct the burner that thesame may be Specification of Letters Patent.

This burner is used in connection with a heater of the type disclosed inmy previous patent referred to above and including briefly a fuel tank 1carried by a supporting frame 2 which frame extends above the fuel tankand carriesthe compartment 3 in which the soldering iron or other toolswhich are to be heated will be placed. A

filling neck 4 is provided for the fuel tank 1 and an air pump15 isprovided so that the necessary air compression may be supplied to forcethe llquid fuel through the outlet pipe 6. The burner which is indicatedin general by the numeral 7 in Fig. 1 is positioned as shown in Fig. 1so thatthe flames will be directed longitudinally through thecompartment 3 and this burner is positioned above the pan 8 into which asupply of fuel will be poured when first starting the heater. Thisburner is of the retort type and it is, of course, obvious that theburner must be heated in order to permit theliquid fuel to be convertedinto gas. Therefore, when first starting the furnace, the pan will befilled with fuel which will be ignited and this fuel will serve to heatthe burner so that when the valve 9 is opened to permit kerosene orother liquid, fuel to flow through the pipe 6 and into the burnerthrough the neck 10, the fuel will be converted into gas.

Thisburner is formed in two sections, the upper section being indicatedby the nun'ieral 11 in F 2 and the lower section by the nituneral 12.The lower section is formed in a single casting and is provided with anend wall 13 and sidewalls 14 which extend parallel from the end wall toa point approximately midway the length of the to provide a pocket 17which communicates with the pocket 15 at one side thereof. Notches 18are formed in the rear end portions of the side walls adjacent the endwall 13 so that the pan 8 may fit into these notches and thus assist insupporting the burner when put in place as shown in Fig. 1. A nozzlesection is cast integral with the side walls and is positioned betweenthe same and provided with a flat and flaring forward or outlet endportion 19' and a trough-shaped rear end portion 20 having notches 21formed in its upper edge for a purpose to be hereinafter brought out. Apost 22 is positioned in the central portion of the flared end portion19 of this nozzle section and serves to divide the sheet of flamepassing throughthe nozzle as will be hereinafter brought out. It shouldbe noted that the nozzle extends beyond the forward ends of the walls asshown in Fig. 3.

The upper section is in the form of a flat plate 23 which rests upon thelower section and has ribs 24 cast integral therewith and extendinglongitudinally of its under face as shown in Fig. 8. A valve housing 25is also cast integral with the plate 23 between the ribs 24 and isprovided with a rearwardly extending neck 26. This valve housing and therear end portions of the ribs 24 will fit into the cutout 15 and reducedlower end portion 16 thereof, and a side arm 27 leading from one of theribs 24 will fit into the cutout 17. Webs 28 are carried by the ribs 24and provided with flaring forward end portions 29, the webs engaging theupper edges of the nozzle section of the lower burner section andtogether therewith forming a nozzle having a tubular rear end portionand a flaring outlet end. It should be noted that the plate 23 isthickened between the flaring outer end portions 29 of the webs 28 andthat the webs are provided with notches 30 which cooperate with thenotches 21 and thus form side openings in the nozzle I gage the flaringend portions 29 of the webs 28 to assist in preventing the two sectionsfrom having longltudlnal movement and the =2 side arm 32 which extendsfrom the forward end portion of the upper section is provided with adepending lip 33 for engaging the extended forward end portion of thelowernozzle section as shown in Fig. 4. It will thus beseen that the twosections interlock,

and therefore, when the securing screws 34 are passed through theopenings 35 of the side walls 12 and screwed into the threaded openings36 of the webs 28, the upper and lower sections of the burner will besecurely connected and cannot have independent movement and further willbe prevented from having any tendency toward warping when they areheated and cool off.

The thickened forward end portion of the upper section is provided witha transversely extendin fuel inlet passage 37 which has its end portionclosed by the screws 38 which constitute plugs to prevent the escape ofthe liquid fuel through the ends of the passage. At one end, the passage37 communicates with an opening 39 formed in the side arms 32 so thatliquid fuel from the pipe (3 may pass through the elbow 10 and upthrough the passage 39 into the passage 37. Branch passages 40 extendfrom the passage 37 upon opposite sides of the burner and have theirrear ends closed by the screw plugs 41. A side passage 42 is formedadjacent the rear end of the upper section and has its outer end closedby the screw plugs 43. It will thus be seen that the fuel which passesthrough the passages 40 will pass through the side passages 42 and intothe valve housing through the passage 44. This passage 44 is closed atits lower end by the plug 45 and intersects a passage 46 formedlongitudinally of the valve housing and having its walls threaded for aportion of its length for engagement by the threads of the valve stem47. This stem 47 extends through the neck 26 and carries a hand wheel 48so that the valve stem can be easily rotated. The valve stem is taperedat its forward end to provide a needle valve 49 which extends throughthe pit 50.

When this burner is in use, the pipe (3 is connected with the elbow 10which in its turn is connected with the side arms 32 of the uppersection. A supply of fuel is placed in the pan 8 and lighted and afterthe burner has been preheated by the fuel placed in the pan, the valve47 will be opened and the fuel will flow through the burner. As the fuelenters the burner it passes through the passage 37 and then will passthrough the passages 40. In doing so, the fuel will be converted into agas by the heat, and therefore, when the fuel passes into the valvehousing, it will be in a gaseous form instead of in a liquid form. Thisgas will pass out through the outlet pit 50 and will be ignited. The jetof flame which will be under compression due to the presence ofcompressed air in the reservoir 1, will pass through the nozzle of theburner and upon reaching the wide and relatively flat outlet end portionof the burner, it will be divided by the post 22 and will pass out ofthe burner in a flat and relatively wide sheet garages offlame,Therefore, the soldering iron or other tools which are placed in thecompartment 3 will be subjected to theaotion of a wide and flat flamewhich is very: hot and 1 will be quickly heated. There has thusbeenprovided a burner which is very efficientin.

operation since theuliquid fuel passesinto the burner across the wideinletend portion of the nozzle and then divides and passeslongitudinally of the burner upon opposite sides of the nozzle'beforereaching the valve housing. The construction of the burner causes thetwo sections to be securely but releasably held in engagement with eachother and prevents them from being warped. The construction furtherpermits the burner to be easily taken apart and cleaned when necessary.
